I have to press the unlock button on the remote of my '97 Z28 for at least 10 seconds before the door will unlock. I just replaced the battery so that's not the problem. It's 17 years old so is it just because it's wearing out or do all old remotes do that?

Just a silly little trick but to get better range and a stronger signal hold your key fob to your chin and press the desired button. By doing this your body actually acts as a ground and intensifies the signal from your fob to the car.

This especially come in handy if you forget where you parked your car in a huge parking lot. People have give me goofy looks while holding my fob to my chin pressing the lock button over and over to honk the horn.

Good luck

I do this with my remote start for my SUV.. I even stick my tongue out in the direction of the SUV.. it really works!!! And it helps with the girls!!!

As far as the remote. the grease was probably diluting the signal or 'shorting' it out
